GMC 2007 Canyon - Manual (Page 184)

If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your dealer for service.
{ CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag system. If this ever
happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger seat
may not have the protection of the frontal
airbag. See Airbag Readiness Light
on page 181.
Battery Warning Light
This light will come on
briefly when you start
the vehicle, as a
check to show you it is
working; then it
should go out.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked right away.
Driving while this light is on could drain your
battery and result in a vehicle that may stall. See
DIC Warnings and Messages on page 198 for
more information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such
as the radio and climate control system.
